Answer:
x = 25
Step-by-step explanation:
Angles in a triangle add up to equal 180
Thus, 180 = 27 + 53 + 4x
We now solve for x
step 1 combine like terms
27 + 53 = 80
we now have 180 = 80 + 4x
step 2 subtract 80 from each side
180 - 80 = 100
80 - 80 cancels out
we now have 100 = 4x
step 3 divide each side by 4
4x / 4 = x
100 / 4 = 25
we're left with x = 25
